About this 1.01ct natural cushion diamond

This 1.01ct natural cushion sits in the classic one-carat band, graded G colour (near-colourless) and SI2 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 1375886001. Listed at 13 retailers as of November 5, 2026, with prices from $3,299 to $5,069, a $1,770 spread on the same certified stone. Washington Diamond lists it at $5,069. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
